FC fiber optic patch cord type

FC fiber optic patch cords are primarily single-mode cables with a screw-on ferrule connector, available in simplex and duplex configurations, and with various ferrule polishing types for different applications.

Overview of F

C Fiber Patch CordsFC (Ferrule Connector) fiber optic patch cords are designed with a metal ferrule and a screw-on locking mechanism, providing a secure and stable connection. They were originally developed for single-mode telecommunications and are widely used in optical distribution frames (ODFs) and high-precision network equipment due to their robust construction and dustproof performance.

Configurations

Simplex FC Patch Cords

Contains a single fiber strand with an FC connector at each end. Transmits data in one direction only, suitable for unidirectional applications such as connecting a single transmitter to a receiver.

Duplex FC Patch Cords

Contains two fiber strands with FC connectors at both ends. Supports bidirectional data transmission, commonly used in high-speed network equipment and server connections. Fiber TypesSingle-Mode FC Patch Cords: Typically have a yellow jacket and a small core diameter (~9µm).

Ideal for long-distance communication with low attenuation and minimal dispersion.

Multimode F

C Patch Cords: Less common for FC connectors but available for short-distance, high-bandwidth applications. Core diameters usually 50µm or 62. 5µm, with color-coded jackets (OM1/OM2 orange, OM3 aqua, OM4 violet, OM5 lime green) for identification.

Ferrule Polishing TypesFC patch cords can have different ferrule end-face polish types to minimize back reflections, especially important in single-mode applications: PC (Physical Contact): Standard polish, reduces back reflection.

UP

C (Ultra Physical Contact): Higher precision, lower back reflection (~-50dB).

AP

C (Angled Physical Contact): Angled end-face (8°) for minimal back reflection (-60dB), often used in high-precision or analog signal applications. Jacket and Environmental OptionsPVC: Standard indoor use.

LSZ

H (Low Smoke Zero Halogen): Flame-retardant, low smoke, suitable for public spaces.

OFN

P (Plenum-rated): Highest fire rating, used in ducts and plenums. SummaryFC fiber optic patch cords are versatile connectors primarily used in single-mode networks, available in simplex or duplex, with various ferrule polish types (PC, UPC, APC) and jacket materials to suit indoor, public, or plenum environments. They are ideal for telecommunications, optical distribution frames, and high-precision network applications where a secure, low-reflection connection is required.
